Junction Box for Solar Cell Component and Solar Cell Component

Abstract

A fission structure type junction box for a solar cell module ( 6 ) and the solar cell module ( 6 ) including the fission structure type junction box. The fission structure type junction box is provided with a main junction box ( 1 ) and a slave junction box ( 2 ). A conductor is set in the slave junction box ( 2 ) and connected with a bus bar of the solar cell module ( 6 ). A bypass diode ( 12 ) and a conducting piece ( 13 ) are positioned in the main junction box ( 1 ). The conducting piece ( 13 ) in the main junction box ( 1 ) is electrically connected with the conductor in the slave junction box ( 2 ). Therefore a fault of a circuit in the junction box does not influence the cell module and the fault circuit is easy to maintain.
